Other RHEL 9 compatible distributions
EPEL 9 officially targets CentOS Stream 9 and RHEL 9. EPEL 9 packages will also likely work with other distributions that target RHEL 9 compatibility. We cannot list specific instructions for all such distributions, but in general the steps needed should look similar to the steps for RHEL 9. First enable the distribution’s equivalent of the CRB repository, then install the epel-release package.
dnf config-manager --set-enabled crb
dnf install
